Nut concept

1, the nut is the nut, screwed with the screw or screw together to play the role of fastening parts, all manufacturing machinery must use an original. Nuts a wide range, we have a common GB, British standard, American Standard , According to the different attributes of the country, divided into carbon steel, high strength, stainless steel, steel and other major types. According to product attributes corresponding to different national standard number is divided into ordinary, non-standard, (old) GB, the new national standard , American, British, German standard. (Such as M8, M16), the United States, the British system with the score or # that the specifications (such as 8 #, 10 #, 1/4, 3), the size of the different, different threads are divided into different specifications. /8)

2, the nut is the mechanical equipment connected to the parts, through the inside of the thread, the same specifications nuts and screws to connect together, for example, M4-0.7 nut can only be used with M4-0.7 screw (in the nut, M4 Refers to the nut diameter of about 4mm, 0.7 refers to the distance between the two threads of 0.7mm); US-made products are the same, such as 1 / 4-20 of the nut can only with 1 / 4-20 of the screw with (1/4 The inner diameter of the nut is about 0.25 inches, 20 fingers in each inch, there are 20 teeth).

Flange nuts and general hex nuts are basically the same size as threaded sizes, except that they are integral with hex nuts and nuts are non-slip, which increases the nut and the workpiece Of the surface area of contact, compared to ordinary nut plus gasket combination, more solid and more force.

Commonly common flange nut specifications are generally below the M20, because most of the flange nuts are used in the pipeline and the flange, so subject to the workpiece, flange nut specifications compared with the nut is less. M20 above some of the flange nuts are mostly flat flanges, flange surface is no teeth, most of these nuts used in some special equipment and special places, the general sales manufacturers do not spot.
